Biography
Kayla Jean Mueller was born in 1988 in Flagstaff, Arizona, in the United States. She attended Northern Arizona University before becoming a worker for the Save Darfur Coalition, an aid group that assisted the suffering civilians of Darfur in the Sudan. She also worked for Palestinian rights and African immigrants in Israel, and in December 2012 she went to Turkey to help Syrian refugees. On 3 August 2013 she was kidnapped while returning to Turkey from Aleppo, and the Islamic State held her as a hostage.

On 6 February 2015, it was reported that Mueller was killed in an airstrike by the Royal Jordanian Air Force in the days following the execution of Jordanian pilot Muaz al-Kasasbeh by the Islamic State, as Jordan launched several airstrikes in Iraq and Syria targeting the group. ISIS showed the picture of a destroyed building and stated her name and hometown, hoping to confirm their credibility. On 10 February 2015, her death was confirmed by her parents, although it is still unknown if she was killed by ISIS or by the alleged airstrike. The airstrike theory is attributed to ISIS propaganda, something that they were infamous for, and US government officials John Kerry and Chuck Hagel state that ISIS and ISIS alone was responsible for her death.
